Chelsea stretched their lead at the top of the Premier League to five points on Sunday when they beat London rivals Arsenal 2-0 as surprise package Southampton went down 1-0 at Tottenham Hotspur.

Unfancied Southampton’s first defeat since the opening day of the season allowed champions Manchester City to stay second, while neighbours Manchester United returned to the top four for the first time in more than a year by beating Everton 2-1.

Diego Costa scored his ninth goal in seven league games to tie up the points for Chelsea after Eden Hazard had converted a first-half penalty.

Costa’s strike was set up by a perfect pass from Cesc Fabregas, the former Arsenal midfielder who joined from Barcelona in the close-season.

Christian Eriksen scored the only goal after 40 minutes as Tottenham won in the league for the first time since Aug. 24, giving manager Mauricio Pochettino a triumph over his former club and successor Ronald Koeman.

Eriksen’s goal enabled Spurs to move up to sixth place.

They are level on points with fourth-placed Manchester United, who shot up six positions with an eventful success against Everton.

Falcao winner

Radamel Falcao scored his first goal for Manchester United in a 2-1 win over Everton on Sunday as the Red Devils won consecutive Premier League games for the first time under manager Louis Van Gaal.

Angel Di Maria opened the scoring for the hosts before United goalkeeper David de Gea saved a penalty from Leighton Baines. Baines had scored 14 penalties from 14 attempts before his attempt at the bottom left was thwarted by De Gea. The England international then picked out Steven Naismith, who put the teams level in the 55th minute.

Falcao, who joined United on loan from Monaco during the summer, sealed his team’s win seven minutes later, slotting home past Tim Howard after di Maria’s shot landed in the Colombian’s path.

“Everton got chances outside the box and they had good shots, but David De Gea was fantastic,’’ Van Gaal said. “Falcao was forcing himself last week against West Ham. I told him to be satisfied about his performances and that the goals are coming. The goals are coming. He will be even better after the international break.’’De Gea made a stunning save in stoppage time to tip over the bar Bryan Oviedo’s left-foot shot from 20 meters.

“I think David is the guy the who deserves this reward rather than myself, he saved us throughout the game and particularly towards the end and the penalty as well so not only him but the rest of the side deserve this,’’ said Di Maria after being named man of the match.

Everton remained in the bottom four but stayed out of the relegation places when bottom club Queens Park Rangers were beaten 2-0 in the other Lon

on derby at West Ham An early own goal by Nedum Onuoha was followed by a second half header from prolific Senegalese striker Diafra Sakho, sending the home side up nine places to seventh.

Mourinho-Wenger feud spills onto the pitch

The long-running feud between Arsene Wenger and Jose Mourinho shows no sign of healing after another high-profile falling out on Sunday, this time the result of a dispute over territory.

Midway through the first half of Chelsea’s ultimately comfortable 2-0 victory over Arsenal which stretched their Premier league lead to five points, it became clear that Stamford Bridge was not big enough for two of the game’s strongest personalities.

Especially when a seething Wenger encroached into Mourinho’s technical area raging about a robust tackle by Gary Cahill on his Chile forward Alexis Sanchez. What happened next was both comical and unedifying in equal measure with Mourinho facing off Wenger and then getting a hearty two-handed shove in the chest for his troubles.

With the crowd in uproar, all that was missing was a theatrical tumble to the ground by Mourinho, who continues to have the Indian sign over the Frenchman he has at various times labelled a “voyeur” and “a specialist in failure”.

While Cahill’s tackle on Sanchez was barely legal, Wenger’s reaction could land him a touchline ban, especially considering that if it had happened on the pitch it would likely have resulted in a red card for a player.

Calmer after the heat of battle, Wenger played down the incident with a dash of humour. “I wanted to go for A to B and some one confronted me without any sign of welcome,” Wenger, told reporters, the faintest of smiles on his lips. “It was a little push.”

Asked what Mourinho, who he is yet to get one over in 12 previous clashes, had said to him, Wenger added: “I don’t listen to what he says.”

Mourinho saw things slightly differently, despite saying the incident was “no problem” and that there were “no outstanding issues” between the pair.

“It became heated because of the game, a big game, big rivals, an important match for both teams. These conditions make a game of emotions… but there are two technical areas, one for me and one for him and he was coming to my technical area and not coming for the right reasons, and I didn’t like that.”
